    DNA中 汞II介导的碱基对:2'-脱氧尿苷5取代基诱导的金属离子结合和双链体稳定性的意外行为†
    摘要:
    汞离子介导的dU–Hg II –dU对的稳定性取决于在嘧啶部分5位引入的取代基。为此,合成了在中心位置经dU修饰的一系列寡核苷酸。使用了普通和新的亚磷酰胺。杂交实验提供了带有非经典“ dU-dU”对的12聚体双链体。在大多数情况下,Hg 2+通过金属离子介导的碱基对的形成来稳定双链体,该碱基对的形成由更高的双链体熔解识别。在掺入双链体DNA的三种类型的dU衍生物中,具有小的脂族侧链的那些对汞介导的碱基对的稳定性仅具有很小的影响,而在侧链中具有三键的那些在双链体加热和冷却期间显示出滞后作用循环暗示与汞离子的三键相互作用。金属离子介导的碱基对的形成被侧链-螺旋堆积相互作用所占据的芳香族侧链的空间所阻断。这些相互作用太强,以至于不能形成汞离子介导的碱基对并在不利的配对位置驱动尿苷N(3)受体原子。

  • Synthesis of 2-Deoxy-β-D-ribonucleosides and 2,3-Dideoxy-β-D-pentofuranosides on Immobilized Bacterial Cells

    Alginate gel-entrapped cells of auxotrophic thymine-dependent strain of E. coli catalyze the transfer of 2-deoxy-D-ribofuranosyl moiety of 2'-deoxyuridine to purine and pyrimidine bases as well as their aza and deaza analogs. All experiments invariably gave β-anomers; in most cases, the reaction was regiospecific, affording N9-isomers in the purine and N1-isomers in the pyrimidine series. Also a 2,3-dideoxynucleoside can serve as donor of the glycosyl moiety. The acceptor activity of purine bases depends only little on substitution, the only condition being the presence of N7-nitrogen atom. On the other hand, in the pyrimidine series the activity is limited to only a narrow choice of mostly short 5-alkyl and 5-halogeno uracil derivatives. Heterocyclic bases containing amino groups are deaminated; this can be avoided by conversion of the base to the corresponding N-dimethylaminomethylene derivative which is then ammonolyzed. The method was verified by isolation of 9-(2-deoxy-β-D-ribofuranosyl) derivatives of adenine, guanine, 2-chloroadenine, 6-methylpurine, 8-azaadenine, 8-azaguanine, 1-deazaadenine, 3-deazaadenine, 1-(2-deoxy-β-D-ribofuranosyl) derivatives of 5-ethyluracil, 5-fluorouracil, and 9-(2,3-dideoxy-β-D-pentofuranosyl)hypoxanthine, 9-(2,3-dideoxy-β-D-pentofuranosyl)-6-methylpurine, and other nucleosides.
